ASP.NET MVC ActionFilter [英] ASP.NET MVC ActionFilter

问题描述

如果是否即使在catch块执行从ActionFilterAttribute类OnResultExecuted方法有人知道？

例如：

  [CookiesActions]
        公众的ActionResult登录（USUARIOS usuario）
[...]
            返回查看（新UsersViewModel（sceUsuarios.Usuario，真实））;
            }
            抓住
            {
                返回查看（新UsersViewModel（新USUARIOS（），TRUE））; //在这里OnResultExecuted解雇了吗？
            }
[...]
 

解决方案

在短：是

您可以用一个简单的日志记录动作过滤器验证这一点。

 公共类LogAttribute：ActionFilterAttribute
{
    公共覆盖无效OnActionExecuting（ActionExecutingContext filterContext）
    {
        日志（OnActionExecuting，filterContext.RouteData）;
    }    公共覆盖无效OnActionExecuted（ActionExecutedContext filterContext）
    {
        日志（OnActionExecuted，filterContext.RouteData）;
    }    公共覆盖无效OnResultExecuting（ResultExecutingContext filterContext）
    {
        日志（OnResultExecuting，filterContext.RouteData）;
    }    公共覆盖无效OnResultExecuted（ResultExecutedContext filterContext）
    {
        日志（OnResultExecuted，filterContext.RouteData）;
    }
    私人无效日志（字符串methodName中，的RouteData的RouteData）
    {
        VAR controllerName = routeData.Values​​ [控制器];
        VAR actionName = routeData.Values​​ [行动];
        VAR消息=的String.Format（{0}控制器：{1}行动：{2}，方法名，controllerName，actionName）;
        的Debug.WriteLine（消息，行动过滤日志）;
    }}
 

如果你把[日志]属性上你的方法，你会看到OnResultExecuted写入甚至当你吞下例外调试。

Does anybody knows if the OnResultExecuted method from ActionFilterAttribute class is executed even in CATCH block?

ie:

        [CookiesActions]
        public ActionResult Login(Usuarios usuario)
[...]
            return View(new UsersViewModel(sceUsuarios.Usuario,true));
            }
            catch
            {
                return View(new UsersViewModel(new Usuarios(),true));//is OnResultExecuted fired here?
            }
[...]

解决方案

In short: YES.

You can verify this with a a simple logging action filter.

public class LogAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        Log("OnActionExecuting", filterContext.RouteData);
    }

    public override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        Log("OnActionExecuted", filterContext.RouteData);
    }

    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        Log("OnResultExecuting", filterContext.RouteData);
    }

    public override void OnResultExecuted(ResultExecutedContext filterContext)
    {
        Log("OnResultExecuted", filterContext.RouteData);
    }


    private void Log(string methodName, RouteData routeData)
    {
        var controllerName = routeData.Values["controller"];
        var actionName = routeData.Values["action"];
        var message = String.Format("{0} controller:{1} action:{2}", methodName, controllerName, actionName);
        Debug.WriteLine(message, "Action Filter Log");
    }

}

If you put the [Log] attribute on your method, you'll see that OnResultExecuted is written to debug even when you swallow the exception.
